Engine no 13, 'Universum'

This is a combination of three Ringbom engines, consisting of 5 cylinders, 3 displacers and 2 power cylinders of which one is double working.

The engine works in accordance with the Ringbom system (the power pistons drive the oscillation of the displacers).

This engine is also made with a balance spring to keep the weight of the displacer as low as possible so that the engine can run on a tea-warmer.

For a change I made a very heavy engine to show that the superstructure of flywheel, cooling plate and pillar (weighing approx. 20 kg) easily allows the hot air engine to rotate around its axle with 2 engines.
The ball-bearing turntable has about 100 balls to enable it to turn with hardly any friction.

A technical detail of this engine is the 2 engines are driven by a double working power cylinder; the upper part is connected with the right displacement cylinder and the lower part with the left displacer cylinder.

The piston must fit extremely precisely in the power cylinder to prevent any leakage; otherwise the efficiency of the two engines will be very low.

It appears that it is very important for a Ringbom engine that the power piston and the displacer are shifted at a relative angle of between 70° and 90°. As a matter of fact this holds good for all Stirling engines.

So the key is to align everything very accurately and to take care that the linkage of the displacer bearing housing runs smoothly. I have also tried to give this big and massive object a beautiful shape - regarding it as Art - with the movement at the centre.

This comprises the rotating movement of the engine and the flywheel around their axle and the up and down dancing of the balance springs.

This engine is named 'Universum' because it resembles the movement of Mother Earth and her rotations in our universe.

    This engine is made to show the builders skill and talent. Enjoy it! There is so much time and hard work invested in this engine how could someone say otherwise? Not to mention the fact that if YOU watched it you must have an appreciation for the work that was done to make this beautiful engine. Right?

    candles are extreem heat?
    and by the way the sterling engin was invented in 1816 by Robert Sterling. they use them on yachts and submarines because there quiet. so its not really a prototype.

    sorry, kinda had to add that sence i never get the chance to sound smart.

  • Those are candles ...

    Those are candles burning at the bottom, thus it's the extreme heat from the candles that's the source of fuel to run the device. Looks cool, but it just another kind of engine requiring an outside source of energy to run. But what a wonderful prototype!! Simply beautiful!!

  • OH! I get it now! ...

    OH!
    I get it now!
    The heat causes the water to expand into steam, then it pushes the piston up and once it reaches a point it cools and it goes back down and then is reheated and again and again!
    I get it!! :D

    Beautiful classical creative engineering design work. Congratulations! Lovely, lovely, lovely.
    If the classical Greeks could have built this engine, they would have built in this way. Masterful!
